This is the lightest down jacket in the world the crown jewel of Crazy's research. The secrets to its ultralight construction are a unique design, which we invented, that allows us to remove every seam and unnecessary centimeter of fabric, reducing weight to the absolute minimum. Despite the radical weight savings, it still provides maximum comfort and freedom of movement. The jacket's outer fabric is an extremely lightweight, bi-elastic nylon with a DWR coating that makes it water repellent. The insulation uses unprecedentedly high quality down: Diamond Down with a Fill Power close to 1000. The down is hand selected one by one to use only the most voluminous clusters. For durability and efficiency, the jacket’s chambers are made with bonding, without seams, to significantly reduce down leakage and further reduce weight. This is the ultimate belay jacket or emergency layer. It includes two hand pockets with zippers for storage and is completely packable into the internal pocket. When you need maximum warmth with virtually zero weight penalty, this is the jacket you reach for.
